Abstract
The utility model discloses a pressure-stabilizing system for an oil transmission pipeline, comprising a single-screw pump and a motor, wherein the motor supplies power to the single-screw pump; the motor is connected with a frequency conversion control cabinet for controlling the rotating speed of the motor; the oil transmission pipeline is provided with a pressure sensor connected with the frequency conversion control cabinet; a crude oil input pipe and a crude oil output pipe of the single-screw pump are respectively connected with the oil transmission pipeline; a block valve is arranged on the oil transmission pipeline; and the crude oil input pipe and the crude oil output pipe are respectively provided with an inlet valve and an outlet valve. By using the pressure-stabilizing system, the pressure of the oil transmission pipeline can be effectively controlled and controlled within a certain range, so that the work efficiency of an oil well pump is ensured, and the yield of crude oil is increased.
Description
Technical field
The utility model relates to a kind of petroleum pipeline voltage-stabilizing system, belongs to technical field of petroleum extraction.
Background technique
In the petroleum production process, oil arrives the energy of petroleum transferring station general using self again from the well head to the metering station.For mechanical oil recovery, its power resources are embodied in the pressure of petroleum pipeline at well head in oil well pump, are called for short " back pressure ".But in the oil transportation process, pressure has loss, and pipeline is thin, circuit is long, oil viscosity is high, and back pressure is big; Pipeline is thick, circuit is short, oil viscosity is low, and back pressure is little.In the oil development design, select pipeline, but through after the exploitation in period, oil well can change according to the back pressure value; Commonly the well water amount increases, and adopts liquid measure and increases, and line pressure increases; Cause back pressure to increase, and back pressure increase, and is prone to cause petroleum pipeline perforation, the leakage of mechanical oil recovery oil well pump, oil pipe leakage etc.; Oil well pump efficient is reduced, reduce oil well output.In particularly producing in the winter time, back pressure is particularly important to the influence of crude output.
The model utility content
The purpose of the utility model provides a kind of petroleum pipeline voltage-stabilizing system, can control the pressure of petroleum pipeline effectively, makes back pressure control within the specific limits, guarantees the oil well ordinary production.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of petroleum pipeline voltage-stabilizing system; Comprise helical rotor pump and motor, said motor is that helical rotor pump provides power, and motor is connected with the VFC case; The rotating speed of VFC case control motor; Pressure transducer is set on petroleum pipeline, and pressure transducer is connected with the VFC case, and the crude oil supplying tube of helical rotor pump is connected with petroleum pipeline respectively with the crude oil output tube; And block valve is set on petroleum pipeline, on crude oil supplying tube and crude oil output tube, inlet valve and outlet valve is set respectively.
The beneficial effect of the utility model is:
The utility model can be controlled the pressure of petroleum pipeline effectively, and it is controlled in certain scope, thereby improves the working efficiency of oil well, guarantees crude output.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Embodiment
A kind of petroleum pipeline voltage-stabilizing system; Comprise helical rotor pump 10 and motor 13, said motor 13 provides power for helical rotor pump 10, and motor 13 is connected with VFC case 14; The rotating speed of VFC case 14 control motor 13; Pressure transducer 5 is set on petroleum pipeline 3, and pressure transducer 5 is connected with VFC case 14, and the crude oil supplying tube 6 of helical rotor pump 10 is connected with petroleum pipeline 3 respectively with crude oil output tube 8; And block valve 4 is set on petroleum pipeline 3, inlet valve 7 and outlet valve 9 are set respectively on crude oil supplying tube 6 and crude oil output tube 8.
Be connected through coupling 11 between motor 13 and the helical rotor pump 10,, between motor 13 and coupling 11, be equipped with speed reducer 12, can effectively reduce motor 13 capacity, energy saving as preferably.
Its working principle is following:
Oil well mouth 1 place's pressure transducer 5 is passed to the frequency variator in the VFC case 14 with signal, inverter control motor 13 rotating speeds, thus the discharge capacity of adjusting helical rotor pump 10 becomes big or diminishes, and makes back pressure control within the specific limits.During use, open inlet valve 7 and outlet valve 9, close the block valve 4 on the petroleum pipeline 3; The back pressure value that records pressure transducer 5 passes in the VFC case 14; According to the size of setting pressure, frequency converter frequency is changed, thereby control helical rotor pump 10 rotating speeds increase or diminish; The discharge capacity of unidirectional screw pump 10 is corresponding to change, and makes back pressure control within the specific limits.As preferably, pressure gauge 2 is set on petroleum pipeline 3, be convenient to force value is monitored.
More than the disclosed specific embodiment that is merely this patent, but this patent is not limited thereto, for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, the distortion of making should be regarded as belonging to the utility model protection domain.
